Withdraw from psychiatrist (6)
I believe the answer is:
shrink
I believe this is a double definition.
'withdraw from' is the first definition.
(I've seen this before)
'psychiatrist' is the second definition.
(informal term for a psychiatrist)
(Other definitions for shrink that I've seen before include "Grow smaller like slang psychiatrist" , "Contract, reduce" , "Become smaller like slang psychiatrist" , "Decrease - therapist" , "Shrivel" .)
